**SPOILERS AHEAD**
Part 25 of IGN's walkthrough of BioShock Infinite.
After finding the first two tears and learning not only that Comstock had both the Lutece siblings and Lady Comstock murdered, but also that Elizabeth is neither Lady Comstock or her husband's child, the two must make their way to Cunningham Photography to find the third and final tear. After doing so and learning that the Luteces found a way to cheat death, Booker and Elizabeth return to the Z.H. Comstock Victory Square to confront Lady Comstock's spirit and gain entry into Comstock House.
